Behavior

• Requires Read permission on concurrent_users.
• Reads alerts from concurrent_users_alerts using the same visibility filter as the Online Users feature. Global admins can see all alerts; other users only see alerts for visible apps.
• Returns only alert configuration fields selected by the handler: _id, name, app, def, users, minutes, email, enabled, condition_title, type, created_by, alertBy, and allGroups.
• Loads members and enriches each alert with createdByUser by matching created_by to the member _id.
• Does not paginate in the handler; the full visible alert list is returned.
• Database/read errors return Concurrent users API error..

Limitations

• Results filtered by user permissions: global admins see all alerts; others see only alerts for apps they have access to
• Maximum 1000 alerts returned in a single request
• Alert definitions cannot be modified after creation; must delete and recreate to change type
• last_triggered field only appears if the alert has fired at least once
